PSX is a PHP framework for creating RESTful APIs. It helps you to build clean URLs serving Web standard formats like JSON, XML, Atom, and RSS. It includes a handler system that abstracts away SQL queries from domain logic, a routing system that executes correct controller method for the location of the controller and the method annotation, and a flexible data system that converts database records into formats like JSON, XML, Atom, and RSS. A lightweight DI container handles dependencies. The controller supports request and response filters that can modify the HTTP request or response, and filters are provided for Basic and Oauth authentication.

YAJL (Yet Another JSON Library) is a small event-driven (SAX-style) JSON parser written in ANSI C, and a small validating JSON generator. It's highly portable, data representation independent, fast, generates verbose error messages including context of where the error occurs in the input text, can parse JSON data incrementally off a stream, and is tiny.

transmission-remote-dotnet is a Windows remote client to the RPC interface of transmission-daemon, which is part of the Transmission BitTorrent client. The application is very much like µTorrent in appearance, and currently supports almost all of the RPC specification.

myPatterns is a lightweight library implementing pattern matching of arbitrary data structures (not just strings) in concrete syntax notations. Default notations such as JSON are pre-defined, but users can override them with new, customized notations for their data. myPatterns is available for C and JavaScript developers, and has already been integrated with querying tools such as JSLINQ and JSONQuery.

image_region_selector is a JavaScript for selecting general polygonal image regions. It allows you to draw lines on a <div> containing an <img>. It detects incomplete or tangled (edge crossed) "polygons" and produces a finished polygon description as vertices or scan lines.

The Java Simple Plugin Framework is a framework for creating and using plugins for programs written in Java. It was built to reduce development time while increasing code maintainability of small to medium sized projects. It completely hides the implementation details of components, so you only use their interfaces. It is only 590k in size. Components may be loaded with only two lines of code. It makes heavy use of annotations. Through usage of generics, it is usually type safe. There are additional plugins to export other plugins by JavaScript, JSON, LipeRMI, XMLRPC, Delight XMLRPC, or ERMI. Plugins may be discovered on the local network through ZeroConf. There is initial support for RDF.
